Keiko and Yusuke from the final episode of Yu Yu Hakusho. This entire episode was so sweet and did a really nice job of wrapping up the series. I love the characters in this show.

This isn't really a kiss, but I love when Sanzo hugs Goku here in Saiyuki Gaiden. I don't think the two have a romantic love for one another, but I don't think it's too far fetched to say that they complete one another either.
